Analog FastSPICE (AFS) Platform

The world’s fastest nanometer circuit verification platform for analog, RF, mixed-signal, and custom digital circuits

 

Verification of innovative circuit designs in involves several challenges. Aggressive schedules are common, driven by competition in demonstrating novel circuits and systems, foundry slot availability, and project budgets.

 

The projects are typically managed by one person who is responsible for the entire system architecture as well as for the detailed design of a large number of subsystems.


Comprehensive verification and analysis of individual blocks frequently becomes the bottleneck in determining achievable specifications, which in turn delays the process of system architecture. Circuit simulation times are lengthy primarily due to the following conditions:

 

Verification of innovative circuit designs in involves several challenges. Aggressive schedules are common, driven by competition in demonstrating novel circuits and systems, foundry slot availability, and project budgets. The projects are typically managed by one person who is responsible for the entire system architecture as well as for the detailed design of a large number of subsystems. Comprehensive verification and analysis of individual blocks frequently becomes the bottleneck in determining achievable specifications, which in turn delays the process of system architecture. Circuit simulation times are lengthy primarily due to the following conditions:

 

  1. The circuit has a large element count.
  2. The ratio of time constants (μs) to simulation time steps (ps) is large.
  3. A strict tolerance setting (such as reltol = 10-4 or 10-5) is necessary to achieve the required accuracy.

 

A nanometer SPICE-accurate simulator with the best possible performance is required to overcome this verification bottleneck. The Analog FastSPICE™ (AFS) Platform from Mentor Graphics has enabled CISL to address these circuit verification challenges and shorten the chip design cycle.

 

The Analog FastSPICE™ (AFS) Platform is the world’s fastest nanometer circuit verification platform for analog, RF, mixed-signal, and custom digital circuits.

 

  • More than 120 companies use the AFS Platform for their toughest circuit verification challenges, including high-speed I/O, PLLs, ADCs/DACs, CMOS image sensors, RFICs, and embedded memory.
  • Foundry-certified to 16nm/14nm FinFET processes, the AFS Platform delivers nanometer SPICE accuracy 5x-10x faster than traditional SPICE and 2x-6x faster than parallel SPICE simulators.
  • For large circuits the AFS Platform delivers >10M-element capacity and the fastest mixed-signal simulation.
  • For silicon-accurate characterization it includes the industry's only comprehensive full-spectrum device noise analysis and a high-productivity Analog Characterization Environment—both of which deliver 5x-10x speedup over alternative approaches.
  • For embedded memory and other array-based circuits, AFS Mega delivers silicon-accurate simulation with >100M element capacity.
